Bi-polar same-color LED devices are described comprising at least a pair of substantially same-color light emitting diodes connected in inverse parallel. The devices are advantageously used in AC powered light strings, e.g., connected in series blocks. Parallel block interconnections of the devices in an AC powered light string are also possible, e.g., where a parallel block of devices is connected in series with other elements in the string. The devices may be used in light strings with or without various current limiting circuits.
